Polycrystalline Al2O3 alumina ceramics oo la habeeyey iska caabin heerkul sare ah

Polycrystalline Al2O3 alumina ceramics oo la habeeyey caabbinta xidhashada heerkulka sare ee muuqaalka leh

Sharaxaad Gaaban:

Alumina ceramics (Al203) waa shay dhoobo sax ah oo u adkaysta xidhashada kaas oo si weyn looga isticmaalo warshado kala duwan.Hababka ugu muhiimsan ee wax lagu dhejiyo ee alaabooyinka dhoobada alumina waa cadaadis qallalan, cadaadis isostatic, dhejinta duritaanka iyo shubista, iwm. Noocyada kala duwan ee alaabta, cabbirka iyo saxnaanta waxay u baahan yihiin habab kala duwan oo wax lagu dhejiyo.Ka dib marka heerkulku sarreeyo ee alaabta dhoobada alumina, kaliya isticmaalka habka wax lagu shiido dheeman ayaa la baari karaa.Nadiifinta dhoobada aluminium ee caadiga ah waa 90% -99.9%.

Waxqabadka dhoobada aluminium oxide

1--Adayg sare

Adkeydka Rockwell ee ceramics alumina waa HRA80-90, oo ka xigta kaliya dheeman ee engegnaanta, aad uga badan birta xirashada u adkeysata iyo birta aan la xirin.

2-- Iska caabin Xiro Wacan

Caabbinta xirashada ceramics alumina waxay u dhigantaa 266 jeer birta manganese iyo 171.5 jeer birta chromium-ka sareeysa.Xaalado shaqo oo isku mid ah, waxay kordhin kartaa nolosha adeegga qalabka ugu yaraan toban jeer.

3--Miisaan Fudud

Cufnaanta ceramics alumina waa 3.7 ~ 3.95g / cm °, taas oo ah kala bar kaliya ee birta iyo birta, waxayna si weyn u yareyn kartaa culeyska qalabka.

4-- Balaadhan Codsiga

Alumina ceramics waxaa si weyn loogu isticmaalaa mishiinada, fiber optics, qalabka goynta, caafimaadka, cuntada, kiimikaad, hawada iyo beeraha kale.

Faa'iidooyinka ceramics alumina:

1--Alumina ceramics waxay leeyihiin sifooyin dahaadh aad u fiican.Lumitaanka soo noqnoqda sare waa mid yar, iyo dahaarka soo noqnoqda sare ayaa wanaagsan.

2-- ceramics Alumina waxay leeyihiin iska caabin kulaylka, isugeyn yar oo balaadhinta kulaylka, xoogga farsamada sare iyo kuleylka kuleylka wanaagsan.

3--Alumina ceramics waxay leeyihiin iska caabin kiimikaad iyo caabbinta birta dhalaalaysa.

4--Alumina ceramics-ku maaha kuwo guban kara, ma fududa inay miridhku noqdaan oo xooggan oo aan si sahlan loo dhaawacin, iyada oo qalabyada kale ee dabiiciga ah iyo walxaha birta ah aan la barbar dhigi karin tayada ugu fiican.

5--Alumina ceramics-ka caabbinta sare ee caabbinta, engegnaanta iyo corundum isku mid ah, waxay gaari kartaa Mohs adkaanta 9, caabbinta xirashada waxaa la mid ah alwaaxyo adag oo adag.
